Try a boil/white wash with no clothes in the machine, but do put soap in, then the soap will work on cleaning the machine, also check the install is corect, that is no back flow of water or smells, check mum/dads/friends washer instal guide. if you use descaler it could break down lots of lime scale and cause a blockage, as you should remove your clothes imediatly and put them to dry, there may not even be a problem with the washer.
